Hydrosart® Membranes are stabilised cellulose based membranes that have been optimised for the biotechnological and pharmaceutical industry. The Hydrosart® membrane is a stable polymer that features a broad pH range.

Hydrosart is also extremely hydrophilic, making it non-protein binding. virtually non-foul and has extremely high flux. Membrane regeneration. storage and depyrogenation can be accomplished by using NaOH even at elevated temperatures.

These features make Hydrosart® an ideal membrane for biological applications. Hydrosart® ultrafiltration cassettes are available in the following nominal molecular weight cutoffs:

• 2 kD
• 5 kD
• 10 kD
• 30 kD
• 100 kD

Applications:

Hydrosart® ultrafiltration membranes are designed for use in the biotechnological and pharmaceutical industries. They can be used for the following applications: Oligonucleotide. proteins (albumin - even with 40% EtOH - . hemoglobin). coagulation factors (factor VIII. factor III). vaccines (tetanus. diphteria). monoclonal antibodies.

Product profile:

Hydrosart® shows minimal adsorption of proteins. viruses. etc. Membrane retention is unaffected by repeated use. The Hydrosart® ultrafiltration membrane can be re-used without any loss of integrity or performance. Hydrosart® ultrafiltration cassettes have been validated to withstand in-line steam sterilization without any loss or changes in membrane retention.
